Name of journal: Cardiovascular revascularization medicine : including molecular interventionsAbstract: BACKGROUND: This study sought to assess target lesion failure (TLF) and clinically driven target lesion revascularization (CD-TLR) through 1 year following second-generation drug-eluting magnesium scaffold (Magmaris) implantation using a dedicated technique (so-called '4 P's' strategy).CONCLUSIONS: Improper sizing and poor lesion preparation before Magmaris implantation appear to be related to TLF during 1-year follow-up.

All rights reserved.METHODS AND RESULTS: The 4 P's strategy stands for: correct patient selection, proper scaffold sizing, pre-dilatation (<20% residual stenosis), post-dilatation. All the patient and lesion characteristics, preparation, and sizing of the device were compared in patients with TLF and CD-TLR through 1-year follow-up. We analyzed 315 patients for this study. At 1 year, there were 14 TLFs and 10 CD-TLRs. The TLF rates were 7.7%, 4.9%, and 4.1%; while the CD-TLR rates were 7.7%, 2.5%, and 3.2% in the undersized, properly sized, and oversized vessel groups, correspondingly. Diameter stenosis (DS) after pre-dilatation in patients with TLF and CD-TLR was significantly greater than in those without TLF and CD-TLR. In patients with a properly sized scaffold, DS after pre-dilatation was similar in patients with and without TLF and CD-TLR. However, in patients with non-properly sized scaffolds, greater post-balloon DS was observed in patients with TLF and CD-TLR.All authors: Galli S, Garcia-Garcia HM, Haude M, Joner M, Lee MKY, Melaku GD, Ozaki Y, Verheye S, Waksman RFiscal year: FY2021 Digital Object Identifier:
